Mode Expansion with Moment Method (ME-MM) to Analyze Dielectric Resonator Loaded CavitiesAbstract
An efficient hybrid Mode Expansion- (ME) Moment Method (MM) or ME-MM is proposed to simulate the eigenvalue problem of multi-layer dielectric resonators (DRs) within cylindrical and rectangular cavities. Resonant frequencies and field distributions for several DRs are presented. The method’s efficiency and accuracy are validated by comparison with commercial software, such as the HFSS, and other numerical methods. Finally, an air gap tunable DR analyzed via shows the ME-MM potential to design tunable DRs and filters.
